The de Warenne family were a noble family in England that included the first Earls of Surrey, created by William the Conqueror in 1088 for William de Warenne, 1st Earl of Surrey, who was among his companions at the Battle of Hastings. The family originated in Normandy and, as Earls, held land there and throughout England. When the senior male-line ended in the mid-12th century, the descendants of their heiress adopted the Warenne surname and continue as Earls of Surrey for another two centuries. Several junior lines also held land or prominent offices in England and Normandy.
